Bees make a buzzing sound, that is caused by the rapid beating of their wings.
that sound comes from them flapping their wings rapidly
Hummingbirds are small bipedal birds recognized for their rapidly fluttering wings. The fluttering of their wings resemble the sound of humming. When they group together, the hum becomes even more recognizable, thus, termed as 'charm'.
Bees make a buzzing sound, because they flap there wings 11,400 times per minute, which makes the sound.
